If you have to maintain a lawn anyway, why not harvest it for energy? The personal lawn harvester coverts lawn turf to pellet fuel that can be used for home heating or power generation.
The mower is powered by the grass pellets it harvests, so you never have to fuel it. A guidance system based on VSLAM and GPS allows for autonomous operation in cluttered and unpredictable environments.
Herbaceous materials such as lawn grass have very similar energy content when compared to woody biomass on a dry material basis, and grass has a shorter carbon cycle and better growth ...

GREENHOUSE ESCARGOT IN SPACE
At astronomical distances away from our home planet, what will be the source of extraterrestrial sustenance for the new pioneers of space? And will “shipping” dried, frozen or preserved food grown on Earth be even feasible in order to provide the distant colonizers adequate nourishment far from the green fields of our home planet? Relying on high technology? Yes, of course, as long as the space traveler has a source of vital nutrition.
It is unlikely there will be verdant acres growing on the surfaces of distant moons or ...
If you sit on a plot of land and have enough surface area to tap into this wealth of free warm water, you just need to circulate and store the glycol somewhere temporarily. For office buildings the ideal place is on the roof, in the penthouse of a new building. To do this, you need to lay glycol pipes thoroughly connected from the subsurface to the tank on the roof and back again to where the heat is needed.
All of this takes planning and special engineering services that can determine how much of the glycol one can realistically ...
Harvesting Electricity from Ambient Turbulence (HEAT)
As anyone knows who has changed a tire along a busy roadway, an incredible amount of turbulence is created by external airflow over and around passing vehicles. This turbulent air is an untapped, kinetic-energy resource; though, it is difficult to harness due to the chaotic intensity and irregular vectors of the energy. A system—HEAT—is proposed to convert vehicular turbulence into useful electric current. This “free” electricity can offset costs of electrical needs such as lighting of roadway features, facilities, or operating systems. Public benefits will accrue from reduced operating expenses for transportation systems ...

Poultry production requires lots of heat and ventilation due to litter producing ammonia, etc. A heat exchanger made of large tubes (thin inexpensive plastic) will be cheap and less efficient, but very practical. Heat recovery will save lots of heating fuel during the baby chicken phase of broiler production.
A prototype using 25 foot 3 inch tubes for home dryer exhaust available at Menards delivered about 50% heat recovery. Such a large device fits easily in a broiler chicken house attic, where attic vents, and condensation drainage under the eve make a very practical match.
Typical heat exchangers are less practical ...

A HVAC zoning system based on a rechargeable, battery operated, wireless zone or room damper and a centralized control system. The system is comprised of three components, a wireless temperature sensor for the zone to be controlled, a wireless, battery operated zone or room damper and a central control system with a web interface to allow users both remote and local user temperature settings. The central controller will act as the thermostat to the HVAC unit, calling for heat or cool as each zone requires. Each zone will have the ability to schedule occupied and unoccupied times and temperatures, ...

"Hybrid Opposite Piston Engine — HOPE attempts to correct certain deficiencies of the thermodynamic cycle and of the mechanism as employed in conventional engine: The cylinder head presents big heat losses and has a complex construction; A lot of exhaust gases energy is lost doe to relatively short stroke; The side force on the piston (pushed by the connecting rod) increases the friction and the wear of the engine; Is difficult to be balanced.
The inconveniences and disadvantages of the conventional engine are overcome by HOPE concept which uses a toroidal opposed-piston configuration, including two stepped piston compressors ...
Our Hybrid Power System HPS-1 changes the game in backup / remote power generation:
Incorporating a sealed, absorbed glass mat deep-cycle battery and an industrial full sinusoidal power inverter, we have been able to reduce fuel consumption by more than 50% over a conventional generator. The addition of an optional 500 Watts of solar panels (also mounted on a mobile platform), creates a truly robust backup or remote power solution.
Without any solar, one 5 gallon cylinder of propane will operate a modern 25 cubic foot refrigerator for 2 full weeks.
With this portable system it's possible to distribute ...
This hybrid solar collector is intended for household use where it's hard to utilize all generated energy if it comes in single form, be it heat or electricity. And where the size of equipment is important. This design combines solar heat collector with photovoltaic cells and provide possibility to regulate proportion in which each energy form is generated. This combination allows to reduce additional waste when household's one accumulation system is fully charged, by switching to other energy form.
System is composed from multiple units with tilt and pan mechanisms to track the sun and maximize system's efficiency. Each ...
